MACHINE FOR THE MANUFACTURE OF PAPER RECEPTACLES.

. J Application filed February 23, 1923. Serial No. 620,639}.

To all whom z't may concern:

Be it known that I, DAVID J. JENNINGS, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Machines for theManufacture of Paper Receptacles; and 1 do hereby declare the followingto be a full, clear, and exact description of the invention, such asWillenable others skilled in the art to which it pertains to make anduse the-same.

This invention relates to machines for manufacturing paper receptacles.The general object of the invention is toprovide a machine adapted tocut the blank for the side wall or body of the receptacle, to form thesame on a mandrel, to apply adhesive material to the paper during theformation to retain the shape given it, and then to remove it from themandrel. A more specific object is to render the machine automatic andcontinuous in its operation to accomplish the rapid and efiicientmanufacture of such receptacles.

In the particular embodiment of my invention shown in the drawings, Ihave provided a machine for manufacturing paper receptacles of a typehaving a tapered or frusto conoidal side wall and disk-like bottom andtop closures. Another object of the invention is to so construct themachine that it may position one of the end closures during theformation by holding it bet ween two parts of the mandrel and causing itto form an interior groove in the wall'of the receptacle, which it maypermanently occupy. Still another specific object of the invention is toconstruct a simple eflicient and positively acting device fortransferring such disk-like end closures from a magazine to the movingmandrel and accurately positioning them thereon previous to forming thebody of the receptacle.

Among still other objects, to become apparent in the followingdescription, is the embodiment in such machine of a system of vacuumpassages for causing the paper to be picked up and tightly rolled ontothe mandrel, and also for use in insuring positive removal of thefinished receptacle fromthe mandrel.

In the formation of such receptacles it is desirable to print certainmatter on the a suitable mechanism and printing couple which may act onthe paper forming the body before it is rolled onto the mandrel, wherebya flat printing member may coact with a corresponding platen, thusinsuring an even impression. 4

The characteristic principles of this invention were set forth in myabandoned U. S. application Serial #259,119 filed May 19, 1915.

My invention is hereinafter more fully described in connection with theaccompanying drawings, the essential characteristics thereof beingsummarized in the claims.

The receptacle which the present machine is designed to form is of thetype illustrated in Fig; 29 on Sheet 3 of the drawings. As there shownthe receptacle shows a side wall A formed from a blank A, illustrated inFig. 30, of such alength that it may comprise more than one turn,preferably slightly more than two turns, held together .by anintervening layer of adhesive material. The receptacle is providedadjacent its lower and upper portions with outwardly extending beads Aand A adapted toreceive the peripheries of paper disks forming the endclosures of the receptacle. The present machine forms a receptacle withthe bottom closure permanently positioned, as indicated at B. To. formsuch a tapered wall, the paper comprising the wall should be cut withits edges in concentric arcs. I have found that-a mandrel revolving insuchan arc may simultaneously cut and roll such blank onto itself. Theends of the blank may be left parallel as cut from a straight strip, ora single corner at A may be trimmed ofi' previous to its presentation tothe mandrel and its platen for convenience in picking up the end ofthepaper by the mandrel.

The general arrangement of the machine is shown particularly in Figs. 1,2, 3 and 4. The frame of the machine comprises side members 1 and 2, andwalls 3 and 4 rising from the base 5, and supporting plates comprisingseveral sections the functions of which will be hereinafter more fullydescribed.

The driving pulley of the machine is designated 7. Fig. 4 illustratespower applied to this pulley by a belt 8 connected with a pulley 9 of a.suitable motor 10. The pulley T is rigid on a shaft 12 extendinglongitudinally of the frame and having bearings 1n the end walls 3 and4. Between the bearings embracing this shaft and extending outwardlyfrom the side wall 1 is a worm 14 rigid on the shelf and meshing withand driving a worm wheel 15 rigid on a vertical shaft 16 having abearing rising from the base and a bearing 17 formed in the top plate.This vertical shaft 16 rigidly carries .at its upper end radiallyextending arms 18 and 18. These revolving arms carry rotatable mandrels20 which are tapered as shown and coact with an arcuate platen 24 toform the receptacles, as will be hereinafter more fully described.

The arms, revolvingwith the shaft 16, cause the mandrels to cut. andform the side walls of the. receptacle from a continuous strip of paperindicated at P. This paper is preferably led from a large roll mountedonupright bearings 26 positioned adjacent one end of the machine, and isperiodically fed across the platen ahead of each mandrel. The severedportion of the paper is caused to wind onto the mandrel by vacuumapplied to passages 27 leading outwardly from the mandrel and inwardlyalong the arms and then downwardly as at 28, the passages 28 joiningwith a pipe 29 connected with a tank 30 from which the air is exhaustedby a pump 31. connected with the-tank by a pipe 32 and driven by asuitable belt 34. A suitable relief valve is mounted in a pipe connectedwith the pipe 32. 28 are alternately put into communication with thepassages 27 and with passages 35 by "alve mechanism to be hereinafterdcscrjibed. the passages 35 acting on the bottom of the receptacle tocause its removal from the mandrel after it is formed;

The. passages The completed receptacles may be carried away from themachine by parallel chains 40 and 41'running over pairs of sprockets 42on opposite sides of the machine guided through the upper portion of themachine on idler sprockets 43, the chain being driven at a speed havingsuch a relation to the speed of the arms that spring clip members 45 onthe chain may embrace the receptacles as they are delivered from themandrel, this speed being maintained by sprockets 46 (Fig. 7 on theshaft 47 driven by a pair of coacting bevel gears 48 and 49 on theshafts 47 and 16 respectively.

Before the paper reaches the platen it is led along a horizontal guideat the left hand end of the machine, so that I may avail my self of thisspace for the purpose of print ing on the paper any label or legend'itis desired to have appear on the exterior of the finished receptacle.The printing mechanism is also driven from the shaft 12 through a wormand gear 50 and 51 on this shaft and on a horizontal shaft 52 respec-.,tively, (Fig. 6) carrying the operating mombers for the printing andpaper feeding mechanism, as will be described. The mandrel is positivelydriven at each end by gearing carried by the arms and actuated bypinions 55 meshing with a large crown bevel gear 56 rigidly carried bythe up or portion of the frame, whereby the r0111 g contact between themandrel and the platen is given the necessary precision and accuracy.

I will now describe the various parts of my machine more in detail inthe following order, beginning with the feeding mechanism, the mandrelsand their carrying arms, the means for applying adhesive material to thereceptacle wall to hold its shape, the means for positioning a bottomclosure in the receptacle during its format-ion, the mechanism forremoving the receptacle from the mandrel, and lastly, the means forprinting on the side wall of the receptacle.

The feeding nwchanism.

A continuous strip of paper from the roll is'led upwardly beneath aguide roller 60 and then over a guide roller 61 having small trunnion.bearings movable in a slot 62 formed in the brackets 63 extendingoutwardly from the frame of the machine and supporting both of theserollers. The paper is then led forwardly over the top plate 64 extendingacross between the side plates 1 and 2. Above this plate 64 is a guideplate 65 terminating adjacent the outer edge of the platen 24, Figs. 5,6, and 19.

The means for moving the paper forwardly is illustrated as slid'ablyreciprocating grippers shown in Figs. 23 and 24 which comprise plates 67rigidly mounted on vertically movable pins 68 extending downwardlythrough slide blocks 69 and each urged downwardly to pinch the paperbetween the top of the block and the plate by a spring 70 mounted in anopening surrounding the pin 68 and closed by a nut 71 threaded onto thispin and slidable in such opening. These blocks are reciprocated by rods72 looping around the same and having a cross piece .7 3 engaging theforward side thereof and having a connecting cross piece 74 adapted toengage the rear side of the block after a period of lost movement tothen push it forwardly. These rods extend through guiding cars 75 in ahorizontal slide 78 actuated by bell-crank levers 79 having bifurcatedends engaging roller-carrying pins 80 on the slide. The bell-cranklevers are pivoted on a shaft 81 and have laterally extendingpins 82embraced by rollers engaging face-cam grooves 83 in the cam members 84mounted on the shaft 52. The gripper slides have laterally extendingribs engaging ways formed in the plate 64 while removable strips 82'embrace the upper sides of these ribs-completing the guide ways.

The paper feeding mechanism thus described operates as follows: Uponeach rotation of the shaft 52, the cams 84 reciprocate the bell-cranks,moving the upper arms thereof and reciprocating the slide 78 which maybeguided in suitable ways 89 projecting inwardly from the side plates 1and 2.. On the inward movement of this slide the ears 76 causes a spring85 o'none of the rods 72 which bears at one end against the ear and atthe other against the rigid collar 86, to be compressed until a smallcam 87 on'the slide 7 8 passes from beneath a ball-bearing in the pin68, permitting the spring 70 to thrust this in downwardly, causing theplate 67 to pinc the aper between. itand the" slide block 69.. hegrippers thus engage the paper at opposite edges and permit it to beadvanced upon the engagement of said grippers by the cross piece 74the-rebybringing said paper a definite distance ac rpss the platen 24.Further advance movement of the slide'78 merely compresses the spring85, and the cross piece 73 leaves the gripper block and the rods slidealong it While the paper is being severed androlled onto the mandrel.The return stroke of the bell crank lever 79 and slide 78 brings thecross piece 73 into engagement with this block just as the cam 87 comesunder the pin 68, raising the gripper plate free from the paper so thaton the return stroke each gripper slides idly along the edgeof the paperstrip. During the cutting of the forward edge of the paper'and rollingof it onto the mandrel the paper is securely held from moving by aseries of clamping pins arranged transversely of the plate 64 adjacentthe platen and illustrated at 90, Figs. 6 and 19. These are slidablycarried in bosses on the plate 64- and are urged upwardly by engagementof teeth 91 on wheels on a shaft 92 extending beneath and parallel withthe row of gripping pins. This shaft is adapted to be given a partialrotation by an irregular cam groove 93 in a block carried by the slide 78 and acting on a bell-crank 94 there being a ratchet rigid on the shaftandactuated by a dog 95 on the bell-crank, whereby, upon each actuationof the slide, these pins are alternately released and raised again tothe. tops of the teeth 91 in which latter position they tightly pressthe paper to' the guide plate 65. This bell-crank 9 1 isconnected by alink 96 with a lever 97 pivoted at 98 and loosely articu lat-ed with adog and carrying arm 99 actuating a ratchet 100 on a shaft 101 havingsimilarly arranged toothed wheels 102 adapted to urge pins 103downwardly into engagement with the paper on the plate 64 to grip thepaper along aline ahead of the pins 90.

Upon each reciprocation of the slide and grippers the paper is advanced,and, as the 1 size and weight of the paper roll varies, it is desirableto provide a take-up for the motion of the paper designed to keep thepaper taut and'yet 'permit its, forward movement.

,This is accomplished by the loose roller 61 sliding in the slopingslots 62.

Mandrels, arms, etc.

Describing next the construction of the mandrels and revolving arms, theshaft 16 has a bearing 17 in a cross plate 19 adjoining the plate 64 andextending between the members 1 and-2 and having an upward cydle.

lindrical extension embraced by the hub of the crown gear 56,- which isrigidly secured to said extension. Above this gear 56 and rigid on theshaft, and accordingly rotatable relative to the gear, are hub members21 formingthe abutting portions of the arms and clamped togetheroverllthe shaft by bolts through outwardly projecting ears 23, thusforming in effect a single rigid arm extending each way from the shaftat the mid- These arms, are preferably of cast metal, to permit formingsuitable strengthening ribs, .and they extend downwardly at their .endsto carry integral bearings for the mandrel and the shafts driving themandrel.

This mandrel driving and supporting mechanism, as shown, comprises ashaft 105 rigidly carrying the bevel pinion 55. This shaft is supportedat its outer end in the downwardly turned portion of the arm and inbearings provided at its inner end by brackets 106 extending downwardlyfrom the intermediate portion of the arm and preferably made integraltherewith. At the outer end of the shaft 105 is aspur gear 107 meshingwith an idler 108, (see Figs. 8 to 12 inclusive) on a stud shaft carriedby the arm. This idler drives a gear 109 on a shank 110 integral withthe mandrel 20. The axis of the mandrel and the axis of the shaft 105are parallel and radial with-reference to the shaft 16.

The mandrel comprises two parts, the main body portion and a base orclamping portion 112 rigidly carried on a hollow shaft 113 havingbearings in the brackets 106. This shaft is slidable through thesehearings and accordingly must be driven in'synchronism with the mandrelwhich I accomplish by providing gears 114, and 115 on the shafts 105 and113 respectively, and positioned between the separated brackets 106.whereby the shaft may drive through an idler 116 meshing with both thesegears.

The taper of "the mandrel must be such that its surface lies in atheoretic conical surface whose apex is coincident with the axis of theshaft 16. Accordingly, the platen must lie in a theoretic cone whoseapex is coincident with the meeting point of the mandrel cone apex andthe axis "of the shaft. To provide for proper operation of the mandrelit is desirable to arrange thedriving gearing as, described, andaccordingly, the gear 56 and its pinion 55 must have their pitch conescorrespond to the cones of the mandrel and platen and their apexes mustmeet onthe axis of the shaft 16 to insure perfect rolling contact of themandrel with the platen.

The mandrel is adapted to cut the blank which when rolled onto themandrel forms the side wall of the receptacle and is adapted to carry adisk of paper so that as the mandrel rolls over its platen, winding theside wall onto itself, the periphery of such disk forces the blankoutwardly making a groove in the side wall and this permanentlypositions it as an end closure. Thisrmandrel with its cutting and bottompositioning features and functions is described, illustrated and claimedin my Patent No. 1273497 issued July 23rd, 1918, and my application No.166,590, filed May 5, 1917 The rotary knives at each end of the mandrelare described and claimed in my application ona device for making paperreceptacles, No- 17 3,920, filed June 11, 1917.

Referring particularly to Figs. 8, 9 and 25 to 28 inclusive, the body ofthe mandrel is tapered and its inner end presents a concave surface to'the convex surface of the clamp 112, whereby a bottom closure B may beripped between the clamp and mandrel and, be distorted from its normalplane while its periphery projects past the surface of the mandrel, asshown in Fig. 8, thus enabling it to coact with a groove 117 (Fig. 8) inthe platen to press the material of the side wall outwardly forming thegroove which it permanently occupies. each side of the platen 24 is anarcuate knife 118 and 119 respectively coacting with cinloo - mandrelrespectively. As the mandrel rolls these knives cut the blank from theoriginal strip.

The end of the blank is picked up by any suitable means on themandrelpreferably by suction, the tubes'27- leading to the end of the hollowshank 110 through a swivel municates with passages 124 leadin connectionindicated at 122 which comto a longitudinal opening 125 in the sur aceof the mandrel. This opening firmly holds the end of the blank againstthe mandrel preventing. slipping and shifting as it rolls,

5 causing it to be tightlyv held thereon. The

arrangement'of the knives and the specific construction of the mandrelis illustrated particularly in Figs. 25 to 28 inclusive. As the largerend of the mandrel is a head member 126 positioned bya shoulder 128 sothat its periphery forms, a continuation of the surface of the mandrel.This head is provided with a series of radial guide passages or groovesin which are slidably mounted the shanks of collapsible bead sectors130. "These sectors terminate in shoulders adapted to be retained andhave their outward movement limited by an overhanging flange 127integral with the head. The sectors are preferably in the nature ofheads on the slides which divide the circle into six'parts and carryaligned outwardly projecting beads 132 coacting when in their expandedposition with'a groove 133 in the platen 24. These beads form in effecta continuous annular rib adapted to press the paper of the wall of thereceptacle outwardly into this groove to form a top closure receivinggroove.

To make this head 132 substantially continuous when expanded and stillpermit it to contract by drawing the sectors inwardly simultaneously, Iprovide at 134 (Fi 27) cutaway portions adjacent the end 0 each sectorformin overlappin surfaces cut substantially tothe center of t e head,as shown.

The'shanks 130 of these sectors are provided with rigid pins 135coacting with cam slots 136 in a flange 137. These cam slots havesurfaces concentric with the axis of the mandrel terminating in inwardlydirected actuating surfaces 138, while the shanks ofthe sectors are cutaway to admit .i the flange 137. On the periphery of the flange is aseries of shoulders 139 adapted when the head is expanded'to take theburden of' the. pressure against coacting' shoulders 140 on each of thesectors. 1

It will be seen that by rotating the flange .a short distance the beadmaybe expanded or collapsed corresponding to the movement given by theoperative portions- 138 of the cam slots. Thus, to rotate this flangeand cause the collapsing or expanding of the bead, I form this flangeintegral with a 128: of the shank: 110, and on this sleeve I providearadially extending actuating memer 142. This actuating member is adated to co-act with the cams 143 and 143 rigidly aflixed on the frame 1and along a continuation 24 of the platen 24 respectively and having asloping surface co-acting with the member 142 to cause a movement of thesleeve with relation to the mandrel by advancing in the first instanceand retarding the rotation of the sleeve in the second instanceaccording to the edge of the cam the actuating member engages as themandrel rolls past the cams 143 and 143. Thus after the blank has beenrolled onto the mandrel, the actuating member 142 engages the cam 143and is actuated to present portions 13.8 of the slots to the pins 135thus withdrawing the bead'and brin 'n it within the periphery of themand i'el which is the position shown in Fig. 26.

In this movement of the'actuating member and its flange the shoulders139 are moved out of the path 'of the shoulders 140.

Outside the flange andmovable beadsec tors, I provide a disk 145positioned by screws 146, and on this disk is carried the knife 121positioned in turn by dowel pins I moving theshaft 113 and clamp 112inwardly toward the shaft 16 as the mandrel comes to the side of themachine opposite the platen. At the inner end of the shaft 113 isprovided a block 150 connected with the shaft and prevented fromlongitudinal movement with relation thereto by'a pin 151 extendingthrough the shaft and engaging an annular groove in the periphery of ashank v152 integral with the block and rotatably embraced by the bore ofthe-hol1ow shaft 113. A suitable ball-bearing is providedat 153 forreceiving the thrust a ainst this block to actuate the shaft and pressthe clamp to the mandrel. This is accomplished by means of rollers 154carried on an upright pin 155 in the block arranged to present therollers to a downwardly turned flange 156 of a cam member 157 secured tothe under side of the rigid gear 56. The contour of this cam member isillustrated Fig.9, and it will be seen that it has a 'concentric portioncorresponding to Q the position of the platen and opposite the rmlyplaten the cam is led inwardly toward the shaft 16 as indicated at 158.'A spring 1601 this ear at one end and against an ear 163 rigid with theblock 150 at the other end of the spring, thus causing the rollers'tocontact with the cam 156 and follow the same, whereby the clamp 112 iswithdrawn from the mandrel a distance sufiicient to remove thereceptacle from the mandrel, which, as before stated, occurs at a timewhen the bead 132 is collapsed. The receptacle is caused to follow theclamp by suction applied to the passage of the shaft 113 from theconnection which is made flexible to follow the movement of the shaft.The inwardly extending portion 158 of the cam ends in an abrupt stepmeeting the outward lead 159 of the cam to cause an abrupt movement ofthe shaft113, so that the portion of the receptacle that overlaps theperiphery of the clamp 112 may be freed from the clamp suddenly as thegrippers, to be hereinafter described, embrace the recepta-- cle tocarry it way from the machine.

The arrangement of the vacuum passages is illustrated most. clearly inFigs. 1, 4, 17

' and 18, where it will be seen that the tubes 27 lead from theconnections 122 at the end of the mandrel and then inwardly anddownwardly to a rotaryv valve device adapted to control the applicationof the vacuum, permitting its most effective/and economic use. The valveshown comprises simply outwardly extending flanges 165 formed integralwith the inner ends of the arms 18 and thereby rotatable with the shaft16. This flange tightly fits the upper surface of the gear member 56,while the passages 28 communicate at 166 and 167 with openings throu hthis gear member covered by the jrotatdble valve flange.

' Paste applying mechanism. I will next describe the means for applyingadhesive material to the body .as it is 4 rolled onto the mandrel.Mounted in a vertical guideway formed in the arms 18 is a slide 170(Fig. 4) rigidly carrying a lat- ;erally projecting receptacle 171substantially closed at the bottom by a roller 172 (Figs. 3 and 10)adapted to be brought into contact with the paper on the mandrel and tobe raised therefrom.

To raise and lower this paste receptacle I provide an arm 173 pivoted at174 to'the slide and mounted on a rock shaft 175 leading along the arm,as shown in Fig. 4, and adapted to be actuated to raise or lower thepaste pot by an arm 176 having a laterally projecting pin 17.7 engagingan arcuate cam 178 mounted on the upper surface of the gear56. Thus, atthe proper time, the roller 172 may be brought onto the paper on themandrel to apply paste thereto between the layers and overlappingportions. It is also desirable to rotate the roller 172 at the sameperipheralspeed as the mandrel to insure even application of the paste.This may be Bottom disk mechanism.

I now describe the mechanism for automatically positioning a bottomclosure in the mandrel previous tothe mandrel reaching the next blank tobe rolled on the platen.

As shown, (particularly in Figs. 14, 15, 16, Y and 32) I have providedan outwardly extending magazine 182 in the form of a cylindrical memberhaving its upperportion cut away to provide, for the greater part of itslength, an open trough. This cylinder is threaded at its iimer end at183 into a ring 184 secured to a vertical block 185 positioned by studs186 secured to the frameand side wall 1. Along the sides. of thismagazine are rods 187 parallel therewith and positioned by ears 188 attheouter end thereof and-secured by nuts to care 189 at the inner end ofthe magazine, the ears being mounted on a portion of the magazine notcut away. On each ear 189 .is shown a pulley 190 over which runs a cord191 secured to a slide 192 fitting the magazine and adapted to urge thebottom closure disks B inwardly toward the machine by reason of theweight 193. The ulley, cord, weight and co-acting parts are uplicated oneach side of the magazine.

The closure disks are placed in the magazine in upright position, makinga continuous series, the innermost closure of which fits against a slide195 vertically movable in tion of the shaft 16, that is, one raisingmovement each time a mandrel passes the magazine.

The magazine is preferably sopositioned that the mandrel passes justabove the same as indicated in broken lines in Figs. 16 and 32. The, cam156 is so arranged that its final outwardly extending portion 203 (Fig.9) is reached by the rollers 154 to give the final outward movement tothe shaft 113, bringing the clamp 112 to the mandrel at a time to grip abottom. closure disk raised by the slide 195. To insure this slideraising, at each time, only one disk to be presented to themandrel, Ihave provided a path, concentric with the mandrel path and secured by anupright member 207 rising from the block.185. A parallel arm 208 extendsfrom the block below the arm 206,and

is also provided with a groove guiding the lower edge of the disk untilclamped by the mandrel.

To hold the disk to the slide and present it to the groove 205, I haveshown a leafspring 209 secured to the upper edge of the block 185adapted to press the disk tothe;

slide, and I so form the spring to clear the mandrel as it moves pastthe same. This spring'is'pf such a length and is so formed that itmaynot press the disk from its path and yet may coact with the slide whenin the position shown in Fig. 32 to insure positioning of it vertically.It will be noted that the shoulder 204 extends horizontally from itsarcuate portion toward the left in Fig. 32, thus registering with thebottom of the groove in the arm 208. i

The disk is thus positioned vertically with relation to the mandrel, andto complete the centering of the disk in the mandrelflmay 1 provide alaterally positioning device as follows: A finger 210 is carried'radiall of the mandrel by the mandrel arm 18 igs. 10,

12,13 and 32). This finger comprises a slide guided inthe end of abracket arm 212 secured-by-fscrews, 213 to a boss 214 on 'adownwardextension at the end of the arm 18. As the movement of the pastereceptacle is synchronized with the action of the mandrel I may soarrange the cam 178 that it may properly actuate the finger 210 asshown. A downwardly extending strip 215 is secured to the lower side ofthe paste receptacle and is provided with a cam surface 216 adapted toengage a pin 217 on the finger 210 to urge the same inwardly to theposition indicated in broken lines at 210*,

Fig. 13, engaging the side of the disk Bf" moving the disk with themandrel. As this positioning finger travels. with the mandrel itcooperates with the guides'206 and 208 and so centers the disk withrelation to the mandrel that its periphery projects evenly from thesurface of the mandrel when clamped therein.

In order that this positionin finger 210 may not interfere with the r0ling of the paper onto the mandrel, l have provided a spring 218 securedat one end to the bracket 212 and at the other. end to the finger 20 andadapted to urge the same outwardly from the mandrel whereby as the pastereceptacle is brought down toward the mandrel, just before the paper ispicked up, the cam surface 216 will release the pin 217 and allow thepositioning finger to be withdrawin to the position shown in solid linesin Fig. 13. In this position suflicient clear- .ance is provided for thepa er to be wound While have shown a on the mandrel. gravity actuatedfollower formoving the bottom disks along the magazine and presentingthem successively to the slide 195, it is to be understood that a springor screw advancing mechanism may be substituted therefor withsatisfactory results.

Receptacle removing mechanism.

Referringnow'. to the device for taking the receptacle, from the mandreland conveying the same from the machine, l have arranged mechanismadapted to intercept the receptacle in its circular path and convey thesame away from the mandrel without interfering with thecontinuous,movement of the latter.

To accomplish this removal Imay use a pair'of conveyor chains-40 and 41heretofore mentioned. As stated, these chains run over sprocket Wheels42 mounted on shafts 220 carriedin suitable journal brackets 221 at eachside of the machine. As shown, the

lower reacheslof the chains run horizontally beneath the.'machine, thenupwardly over one pair of sprockets 42, shown at the extreme right handin Fig. 3, to one pair of sprockets 43, and then horizontally across thetop of the machine just beneath the path .of the mandrel, and thenceacross the other pair of sprockets-43 and downwardly across the otherpair of lever sprockets 42, as

shown in Fig. 4. These chains are preferably co'nnectedby rigidtransverse carriers 222 suitably secured -to the chains and pivotallycarrying rotatable plates 223, which carry the spring clips 45 adaptedto embrace the finished receptacle.

As shown, this,chain is driven by the sprockets 46 (Fig. 7) previouslymentioned, deriving motion from the shaft 16. The speed of the chainsand the spacing of these receiving clips is such that the clips arr1veat the point substantially above the sprockets 346 just as the mandrelclamp is separated most widely from the mandrel body, as indicated inFig. 9, thus bringing the receptacle and the clip together. The chainmoves slower than the mandrel, whereby the receptacle is thrust intothis spring clip and the mandrel continues its movement, passing around.its path; ahead of the receptacle, which isentirely freed from both themandrel and clamp 112as the rollers 154 pass off from the "recedingportion 158 of the clm 15c.
